The skin/leather is the outer envelope of an animal and is formed by dead cells that have hardened. With tannery it becomes solid and resistant to wear and tear. The hamster (calf) is trimmed to remove hairs, cleansed from the flesh and then soaked in solutions of plant extracts containing tannins or chromates. The end of its processing ends from a mechanical point of view depending on the use.
The leather market is a difficult and demanding choice. This is because the leather remains a living body that is extremely sensitive in its maintenance and cleaning.
The leather to take its final form is treated with special chemical finishing (oil) and dyed. Lubrication and dyeing helps tanner to cover skin imperfections.
Genuine leather must have all those physical qualities (nerves, knives, pimples, sores, etc.) that stand out from the technical-synthetic leather (leatherette).

The leathers are divided into two categories:

  • Suede
  • Glase.

The suede is essentially the inner side of the skin, treated on a uniform fluffy surface and used as the outside of the garment.
In a glossy nappa leather the outer side of the skin is also used as the outer side of the garment.

The suede are divided into 3 categories:

  1. Castor (having outer pile surface)
  2. Nobuck (shaved light fluffy surface)
  3. Muton (they have fur on the inside)

The skins/leathers used mainly for the manufacture of a garment are: pork, lambs, goats, sheep, calves, oxen, goats, camel (mainly in bags) and rarely antelope or reindeer. Snakes are primarily used to make accessories.
We must always keep in mind that skins derived from animals that live and move freely in nature are more resistant and more resistant than those from animals in a restricted space as they live and grow in conditions of constant humidity and lack movement.
